The A-750 is built for tight spaces and ANSI-style pumps — a design that adapts to most smaller equipment, with three different radius surfaces for indicator readings. It fits shafts or hubs up to 2.8" and expands to 9" — the bracket assembly rotates with as little as 3" of shaft-to-base clearance. ½" thick.
Like every ALINE set, the A-750 uses the reverse-indicator method: no batteries, no calibration, nothing to charge or reset between jobs. Set the brackets, turn the shafts, read the dials.
Any millwright can learn the procedure in a single shift. Built for the close-clearance jobs a bigger set can't physically get into.
